Referring now to the drawings in detail, my improved automatic metering device is adapted to be attached to a, supply line 2 and is adapted to discharge througha dispensing line 4 provided with any suitable type of valve-controlled dispensing outlet. The device, in general, comprises a valve casing 6 and a meter and meter mechanism 0. By referring to Figure 5, itwill be seen that the valve casing forms a housing for a valve aucnes seat l8 against which a valve I2 is adapted to close, being normally pressed to closed position by a spring l4 surrounding the valve stem i6 connected to the valve II. The construction of the valve may be of any desired form. Thisvalve stem projects outwardly through a packing it of the ordinary type. The upper portion of the stem is provided with a collar 20 adapted to engage a forked head 22 on an operating arm 24 provided with a handle 26. This handle is pivoted at 28 to an upstanding stationary arm 30 mounted rigidly on the housing 6 of the valve. The outer extremity of the valve stem i6 is provided with a series of perforations adjustable to receive, as by a pivoted pin 32, a link 34 in turn is pivoted to an adjustable head comprising a pin 35 on a For purposes of adjustment, the outer end of this rod 38 is threaded and slidably receives the head, the adjustment being made by oppositely disposed nuts 44 and 42. The second link 44 is pivotally connected to the cross pin it and the opposite end of the link 44 is'pivotally connected toa pin 46 mounted on the housing i of the valve. The arm 30 is detachably mounted on top of the valve 6 bymeans of an encircling collar 4. held by means of a screw 5.. A spring 52, interposed on the underside of the handle 26 and connected by means of screws to the arm 30, is arranged to normally hold the handle 26 in ele vated position as shown in Fig. 5. The discharge side of the valve housing 8 connects with a pipe54 which discharges into the inlet pipe I of the meter mechanism. The metering mechanism is of any desired type of volumetric displacement construction, such as the well- I prefer to mount the meter setting mechanism,

including the dials; and the hands, andthe mechanism for automatically stopping the flow through the meter when a predetermined quantity of liquid has been passed through the meter, and also the automatic quantity repeat mechanism for the meter, in a housing immediately on top of the meter housing itself. To this end the upper portion of the meter housing proper, 54, is formed setting shaft 02 and a control shaft, the latter beingprovided with a control knob 48 rigidly flat and thereis bolted thereto a second housing fastened thereto. In addition, the control shaft 1 04 1s provided with a clutch member I in the formofasleeve'whichispinnedtoshaftflby' meansofascrewllwherebywhentheshaft is moved endwise the clutch sleeve II will partwo pawls are each provided with a cut-out in which is located apin l8 and II which limits the upward movemmt of the pawls under the tension of the intermediatcly located spring II which is treme opposite end of the dial settingshaft 02 lodgedintbeboreorgrooveinwhichthesepawls slide. Theouterends of these pawls are provided with a tapered surface as at-fl' (see Figure '1)- whereby such tapered surface may ensur a correspondingly tapered surface on a clutch face hereinafter described. The clutch is dhposed between twoopposed clutchf members 04 and 00 which are respectively loosely mounted on the 1 shaft 04 but are held from lateral movement by a finger 00 securely mounted on the main frame of the housing 00 by means of a'screw 00. These fingers are identical. The lower portions of these fingers fit in an annular groove ,02 whereby to hold-these sleeves .04 and I0. fromiateral movement while permitting their turning. The faces of the clutch members 04 and 00 are. provided with ratchet teeth 24. and arranged to engage the-pawls '12 and 14 respectively so that when the handle 00 is pulled to the left, as shown in Fig. 4, the pawl 12 will engage the'teeth 04 of clutch 04 tolock the sleeve 00 to the clutch 04 whereby to cause counterclockwise rotation of the clutch 04 upon corresponding rotation of the turning knob 00.

" The teeth on clutch 00 are formed so that when sleeve". is shifted to the right. as in -l"ig. 4,

The dial setting shaft 02 is provided with a sprocket wheel I02 which is fixed thereto to rotate therewith, and a chain I, or drive, extends from wheel I00 to this sprocket wheel I02, so that when the shaft 04 is pushed inwardly and turned counterclockwise, rotary motion will be conveyed to the dial setting shaft 02.

same being connected'thereto by a key Ill.

Suitable screws H2 aflix a small dial plate Ill Adrum H0 is disposed to surround the outer periphery of the gear I00. Sleeve I carries a sprocket Ill splined thereon, the sprocket-being driv'ingly connected as by means of a chain 22, with the sprocket portion .00 of the clutch element 04. The drum II, as

shown clearly in Fig. .4, is Journailed for free rotation on the shaft 02. This drum, on its outer periphery, carries a fast moving hand II.

' which is aillxed thereto by suitable screws I20.

The fast moving hand H0 is provided with an inwardlylextending. arrow J22 adapted to cooperate with the small, dial face Ill.

The drum 0 carries at the front portion of its periphery a spring socket ll in'which is lodged a bail I20 normally pressed inwardlyby means of the coil spring I2lto engage the teeth I of the gear Ill so that when the-dial setting shaft 02 is turned counterclockwise by means of the controiknob 00, as hereinbefore described, the

- collar I will be correspondingly turned, which will turn gear III to turnthrough the teeth and pawl I20, the drum II which. in turn, correspondingly turns the large hand II. and the arrow I22. Since this is a counterclockwise turn it will turn counterclockwise until the cam shoulder I10 of the cam face strikes the plunger. I02

on the drum of theslow hand, hereinafterdescribed, whcrebythe fast moving drum will then pick up the slow moving drum and move the slow moving drum counterclockwise until the slow movingdrumhitsastophereinafterdescribed,

at which time both hands will have returned to zero setting.

To um end,-on the sun setting shaft or adjacent the fast movng drum III is loouly mounted a sleeve I20 which has an enlarged hub III through which screws Ill pass for holding a dish shaped housing I02, which extends forwardly and is adapted to carry at its outer-face, a slow moving operator's dial I.

This gear is provided with radial teeth -Ill'adaptedtonormallybeengagedbyaball I02 mounted in a ball cup IN'carried by drum Il0,aspring I" pressing theball normally in engagement with the teeth I00 of gear I". This drum I00 constitutes the slow moving drum. This drum is provided with a hub which is journalled on a projection of sleeve Ill. The drum I isprovided with a transversely extending bore I00 in which there is lodged a plunger I02,

which plunger is provided with another bore- I (Fig. 12) in which is lodged a coil spring I00, the rear end of the spring pressing against the dish shaped plate I42 whereby the plunger I02 is resilientlyforced outwardly against the faceofacam lilontherearface of fastmoving drum III. Thiscamisprovided withasharp shoulder I10 which constitutes a stop to engage the. springplunger I02 as hereinbefore described. It will thus be seen that if the fast moving drum is moved counterclockwise until the perpendicular shoulder I10 strikes the plunger I02, it will thereafter move the slow moving-drum counterclockwise.

Ongthe periphery of the slow moving drum I00 islikewise moimted a slow moving hand I12 which extends radially and forwardly outwardly.

The rear face of the slow moving hand I12 is provided with a rearwardly extending arm I14 providing a perpendicular shoulder I10 adapted -to strike against a spring-p plunger I12 housed'within a sleeve Ill suitably mounted in a stationarypart illofthemainframeof the I housing, so thatwhen the slow moving hand I12 will have contacted the stop'l12, both hands willc ometoastopamithiswillc'orrespondto the aero setting position of the hands.

' Dial setting able dialswhich are the operator's dials. These 15 are the dials which are adjusted for the purpose of setting the predetermining These dials are I44 and "4 respectively and have hereinbefore been referred to. The outer operator's dial I44 ismounted onthe dlshshaped plate I42 torotate with the hub I20 whereasthe inner operators dial H4 is mounted on the hub I05 to rotate with the shaft 52. The outer me'rator's dialis graduated from zero to two thousand (2000) gallons, whereas the inner operator's dial isgraduated from zero to fifty gallons. The outer operator's dial is adapted to cooperate with a stationary arrow I90 fixed upon the plate I54, while the inner operators dial is adapted to cooperate with arrow I22 on the fast moving hand III, as hereinbefore described.

Setting the dials for any predetermined quantity from one to 2000 gallons is a simple matter, easily and quickly accomplished. Err example,

left, to-wit: counterclockwise. This, through the sprocket gearing I00, the chain I04, the sprocket I02 will operate the shaft 52, its hub I05. through the control dial "4 in a counterclockwise direction until the I5 mark on the dial coincides with a pointer I22 on the fast moving hand, which, of course, is at the zero position. This setting having been accomplished, the control knob is then pulled outwardly to the left, viewing Fig. 4. so as to bring the clutch into contact with the clutch 44 in order to connect up the driving sprocket 05 and its chain 99 with sprocket I0! splined upon the hub I25. As hereinbefore described, this hub I25 carries the gear I45, and also carries the dished plate I42, which carries the outer operator's dial I44, hence this outer dial will likewise be turned counterclockwise rmtil the arrow I90 coincides with the 400 gallon graduation thereon.

' Mounted on the setting shaft 52 is a fast moving cam I02 which is pinned thereto by a screw I04. In addition, a slow moving cam I05 is mounted for rotation on sleeve I35, being fastened to it for rotation therewith by means of pin I05. Each one of these cams contains a peripherally dis-' posednotch such as 200 and 202, which are adapted to cooperate with stops 204 and 200 rigidly carried by a sleeve 200 turnable on and wlthrespecttoashaftfllhavingina stationary bracket 2l2 carried by the frame of the Asshown clearly in Fig. 5, these rods 220 and 222 pass freely through the perforaiions-in the bracket 2I2 and in the bridge piece 224,butcollarsaround the rods above and below thseopenings at each end, provide abutments between which the coil springs 220 are housed. As shown clearly in Figs.

'l and 8, the bracket arm 224 is providedwith a central hub 225 inwhich islodged a shaft 220 rigidly carrying'at its oppofite end anarm'222 having a shipper rod 224'connected therewith,

which contacts in anannular groove 205 of the central or intermediate'clutch 50. In this construction,nomatterwhichwaytheclutchisshiftedtocorrespond with theinwardorontwardpush of the control knob 55, the shipper knob-224 is mhvedtotheright,ortotheleft,toturnthecon nectingrodultodepresseitherendofthearms of the bridge piece 224, which in turn, through the spring and rodconnections 225 and 225, depresses either end of the bracket, 2 I4 to thereby swing the bracket about its pivot 2| 0, whereby to pull'the stop arms 204 and 200 out of contact with the stop catches 200 and 202 on the cam, thereby releasing the cams for rotation.

By means of this construction the springs 225 function to maintain the bridge piece 224 in central position, which returns the rod 220 to central position and thence causes the shipper rod to return the clutch 50 back to central position and out of contact with the reversely disposed clutches 04 and 05.

The oscillating bracket 2I2- has a downwardly depending arm 220whichcarries at an outwardly extending portion 240 an adjustable screw or stop 242 (see Fig. 7) which is adapted to cooperate with a locking bar 244 connected to the adjustable rod 20 on the valve mechanism (see Fig. 5). The stationary frame of the machine carries a secondary frame 245 which forms a support for a plate 240 which plate is arranged to straddle the control bar 244 and has a cut-out portion 250 in which the adjustable stop pin 242 depends.

On the bar 244 is a raised longitudinally extending shoulder 252.which is adapted to cooperate with plate 248. This plate 248 provides a sharp shoulder 254 adapted to cooperate with another sharp shoulder 255 formed by junction with the raised portion 252 and the remainder of the locking bar 244. The bar 244 is maintained continuously pressed upwardly by means of a plunger 255, Figs. 5 and 6 resiliently pressed upwardly by means of a spring 250 in a housing on a portion of the bracket auxiliary frame 245, so that when the nozzle valve lever 25 is depressed, as shown in Fig. 6, the same will pull out on the control bar-244 to pull the same to the right. as viewed in that figure, so that the edge of the sharp shoulder 254 on the plate 245 will contact with the corresponding sharp shoulder 255 on the raised portion 252 of the control bar, whereby to bar 244 to the left, as shown in Fig. 6. This control bar is released automatically by the action of the rotating cams I05, I02, to such a position that the notches200 and 202 thereof register with the stop members 204 and-205 at which time the stop members will be spring-pressed inwardly to shift the pivotal bracket 2I2 about its axis 2I0. Simultaneously, when this depending arm 220 is likewise shifted under the action of the springs 225, which overcome the tension of the small spring 250, thereby forcing the pin 242 to move downwardly to press the locking bar 244 downwardly against the tension of this spring 250, thereby releasing the locking edge 255 of the bar 244 from the locking edge 254 of the'plate 240 so that the control bar 244 then shifts automatically to the left to permit thevalve I2 to close under the action of its spring I4. The motion of the bar 244 to the left is caused by the spring tension of-the valve I2.

The meter shaft 55 extends upwardly through the casing 00 and makes a detachable clutch withvthe shaft 252, which, at its upper end, can-lei a gear 254 meshing with gear 255 pinned to shaft 250, which is turnable in part of the'frame 210. This shaft 255 likewise carries sum . 282 thereoL'hence the disc 2, 20' turns with the shaft 2 through the friction chitch'2l2r I ByreferringtoI-igsl3and14itwillbeseenthat satheinnerdiscfllisprovidedwithanotchfll,

Cam II, which is the slow moving cam, is larger in diameter than the fast moving cam 182; The former is provided with a notch 2" having a step 2.2 which has a slightly greater .radius than the cam I96. In other words, if the cams I92 and I! were superposed axiallythe stepin the latter cam would extend slightly beyond the periphery of the former. Cam "2 is formed with a plain peripheral notch as shown at 2". r Y

Pawl or stop 2 is adapted to cooperate with cam II, the cam serving to retain the stop 226 and also to the stop 2" in withdrawn or cocked position, the stop '2 being held entirely out of contact with its cam., This relation is maintained until the second last transfer of motion to camlliis accomplished, whereupon stop 206 will ride into engagement with the step 202' and the pawl 2 will approach the periphery of cam 282. -'It is preferably retained from contact therewith because of the fact that this cam rotates at a comparatively high speed and if the stop engaged the cam, wearing of the cam surface would follow.

At the last transfer of motiom the step 202' is moved from its pomtion under the pawl 206 and the deep portion of the notch moves'lnto position under the pawl, but the latter does not engage in the notch because at this point the pawl 2 engages the periphery of cam I92. Further rotation of the cam I92 brings notch 200 into alignment with the pawl 2 and'the latter seats therein. coincidentally with this operation, pawl 20 drops into the already aligned notch 2'2 and dispens ng is Aninspecfionofl'igure'lwilldisclosethat the motion of stop'2l6 from the periphery of the cam ili tothe' step 2l2' will cause a depression of stop or tappet 2l2 with the result that the shoulder 256 is released from its engagement with shoulder 254 and the bar 2 will move to the left under action of the valve until the next shoulder 256' engages shoulder 254. In this position the valve willhe partly closed and theflow of fluid will he reduced so as to pre- -ventspillageoffluidduetoatoogreatrate,of

discharge.

Likewise, motion of stop 2 from the periphery of cam 292 into notch 200 and the motion of stop 2 into notch 202 produces a second depression of bar 2 and elfects the release of shoulder 256' from the restraint of shoulder 25! with the result that bar 2 is freed for a second leftward motion under action of the valve spring and the valve will be permitted to close.

Thus, it will be observed that the flow near the I completion of a dispensing operation is first reduced and then finally terminated. The minimum quantity of fluid discharged at the slow rate of flow may vary but it is preferably fifty gallows. This is accomplished in the following manner :I

It is apparent that in the final position, the notches 200-202 and pawls 204-206 must be in alignment, whereas at the start of the operation the notch 200' will be displaced from final positionin a counterclockwise direction (Fig. 7) .by.

from 1/50th to 49/50ths of a revolution depending upon thegallonage to be delivered, while notch 202 will be displaced in a counterclockwise direction'anywhere from 1/40th to 39/40ths of a revolution. The transfer mechanism is always-rcturned'to the position shown in Figure 13 ratchet I46 and cam I92 will remain at the zero position. At the end of the first revolution of shaft 62 and indicator II6, cam I96 and indicator I12 will move up 1/40th of a revolution, equivalent to one notch of the ratchet. The second revolution of shaft 62 will, through the transfer, move the-step 202 into alignment with stop 206 so' that during the next and final revolution of shaft' '62 the discharge of liquid will be carried on at-areduced rate until the last transfer is 'accomplished. At this time both stops 204 and 206 will bein position adjacent to the notches 200 and 202 respectively and, as a result, they will be forced into engagement therewith to stop the now.

If the delivery involved had been any amount between 150' and 200 as for instance 199, the cam I92 would have been originally displaced 49/50ths from its zero position and would occupy this position at the time eachtransfer took place with the result that when the transfer of cam I96 'from'the' position in which the step 202' is aligned with the stop occurs, the cam I92 would still have 49/50ths of itsmotion remaining to be made after50 gallons had already been discharged at the slow rate. Consequently, an additional 49 gallons would be discharged at the slow rate making a total of 99 gallons delivered at said slow rate as against 100 gallons which had been previously delivered at-the fast or maximum rate. a Y

- Operation To set the dials to deliver 416 gallons, the first operation isto set the hands of the customer's dial to zero by pushing in upon the control knob and turning it counterclockwise. In the manner hereinbefore described, the hands will be turned to zero, at which time they will automatically and positively stop squarely at the zero mark. In order to set the customer's dials to the proper amount, say 416 gallons, the operator still continues to turn thecontrol knob counterclockwise, whereby through mechanism hereinbefore described, the smallcentral customer's dials II4 of the predetermining mechanism carrying the numeral I6 coincides with the small pointer. I22.

The next operation is to pull out on the control knob 66 and turn it counterclockwise, which, through the clutch mechanism breaks the driving connection with the chain I04 and makes driving contact with the chain 99 to thereby turn the intermediate dial I44 on the slow moving drum in the counterclockwise direction until the 400 gallon mark on this dial registers with the arrow I90 on the stationary face plate or dial. From the foregoing, it will be noted that a large single knob controls the setting of all three dials and that this knob is always turned in the same direction, to-wit: counterclockwise. If the control knob 66 is turned clockwise, it will be ineffectual to turn the sprockets either 98 or I00, due to the clutch teeth. They will ride ineffectually over the clutch teeth of the corresponding member. It will be further noted that this knob 66 automatically returns to central position when released after setting, due to the operation of the springs 226, as hereinbefore described.

Now, to start the flow of liquid after the meter has been given a predetermined setting, the handle 26 is pressed down and as the flow progresses. thecustomer's dial hands advance clockwise until the exact quantity of 416 gallons has been discharged. At this point the flow is automatically stopped due to the fact that the two cams I92 and I96, which have been driven in clockwise direction during the operation of the meter through the train of gearing hereinbefore described, will bring the cut-out notches 200 and 202 opposite the stops 204 and 206, which through the mechanism hereinbefore described,

permits the locking mechanism on the control bar 244 and its 'plate 248 to be released to permit the valve to be spring-pressed to closed position. AI: the end of the delivery, the customers dial hands will indicate a delivery of 416 gallons corresponding with the amount for which the predetermining dials were set. Figure 3 illustrates the position of the customers dial hands and the predetermining dials at the end of the 416 gallon delivery.

If the same quantity of 416 gallons is to be repeated, it is only necessary to return the customers dial hands to zero by pushing in on the control knob 66 and turning the same in a counterclockwise direction as hereinbefore described.

After these bands have thus been returned to to 225 gallons, the firstoperation is to return' the customers dial hands to zero as hereinbefore described, and then advance the small central predetermining dial IE4 in the manner hereinbefore described, from 16 to 25, and then return the intermediate dial I44 to zero and advance it to 200. If the quantity of 416 gallons is to be changed to 510-gallons, the first operation is to return the customers dial hands to zero; next return the small central dial to zero and set it to 10, then advance the intermediate a dial I44 from 400 to 500 gallons. If the quantity of 416 gallons is to be changed to 35, the first operation is to return thecustomers dial hands to zero; next advance the small central dialfrom. 16 to 35 and then return the intermediate dial to zero.
